Hello,
    I am using pvm3.3.10 on the CM5E and suffering from the memory leaks.
The "Instruction Unit Local Heap" (ILH) in the result of the cmps command
always grows rapidly and the program finaly stopped.
This occured any programs including the examples provided by
the distribution, though the computated results themselves were fine. 
I used cc and gcc2.7.2 to compile the pvm and my program,
but any combinations gave same results.
    When I tried on the Sun4 clusters, such a problem
did not happen and the program size was nearly steady.
Since this problem does not happen when the use of the pvm is diabled
in my program, I think the pvm is not correctly implemented for the CM5.

Are there any remedies ?
